I've tried my hand at affiliate marketing before and failed. How would this help me?
If you've tried your hand at affiliate marketing in the past and failed, THERE IS A REASON.
Success comes from understanding all the variables that go into making sales and leveraging those variables to their fullest extent. The SEO built into your site, the quality of your written content, the information you put into your written content, the keywords you target, the way you displayed products in your post - all of those things contribute to (or harm) your success.
I'm going to break those variables down for you in a way that will make them easy to understand and apply to your own online work.
